BRD2 and Infertility: In a randomized controlled trial (RCT) of 205 infertile couples with a female partner < 43 years and with AMH ≥ 1.2 ng/mL and Day 3 FSH < 12 IU/L/, Forman et al. reported that during embryo selection using comprehensive chromosome screening, the transfer of a single euploid blastocyst results in ongoing pregnancy rates that are the same as transferring two untested blastocysts while dramatically reducing the risk of twins [42].
